Tire tread



FIG. 1 is a side perspective view of a tire tread showing my new design, it being understood that the tread pattern is repeated throughout the circumference of the tire tread, the opposite side being the same as that shown;

FIG. 2 is a front elevational view thereof, the opposite side being identical thereto;

FIG. 3 is a side elevational view thereof, the opposite side being the same as that shown; and,

FIG. 4 is an enlarged fragmentary front elevational view thereof.

In the drawings, unshaded portions form no part of the claim.

The broken lines defining the sidewall, inner bead, tread lug sidewalls, the peripheral boundary between the tread lugs and the tread grooves, and the peripheral boundary between the claimed tire tread and the sidewall depict environmental subject matter that forms no part of the claimed design. 

CLAIM The ornamental design for a tire tread, as shown and described.
